Abstract
Very soft, launderable polyurethane foams for pillow and other bedding applications are made using a quasi-prepolymer of diphenylmethane diisocyanate and a polyether polyol having a high oxyethylene content. The quasi-prepolymer is reacted with isocyanate-reactive components that include a certain monoalcohol but is devoid of or nearly devoid of a polyether polyol having a high oxyethylene content.
